The TPS2561DRCR from Texas Instruments is a dual-channel precision adjustable current-limited power switch with active-high enable. Supporting 2.5V to 6.5V operation, each channel provides an adjustable current limit from 250mA to 2.8A via external resistor, with 44m\u03a9 on-resistance MOSFETs and 3.5\u00b5s overcurrent response time in a VSON-10 package.<\/p>\n

Each channel features an adjustable current limit from 250mA to 2.8A (set via external resistor) with \u00b17.5% accuracy, a 44m\u03a9 high-side MOSFET, and independent enable\/FAULT pins. The 3.5\u00b5s overcurrent response time protects against short circuits and heavy capacitive loads. Built-in soft-start minimizes inrush current during turn-on. The device meets USB current-limiting requirements and is UL listed, CB and Nemko certified.","working_principle":"The TPS2561 operates through four key subsystems: (1) Current Limiting: Each channel has a precision current-sense amplifier that compares the MOSFET current against the limit set by an external resistor on the ILIM pin. When the limit is exceeded, the device transitions to constant-current mode within 3.5\u00b5s. (2) Power Switch: A 44m\u03a9 N-channel MOSFET per channel provides the power path, controlled by the EN pin. The soft-start circuit controls the MOSFET gate voltage ramp to limit inrush current into capacitive loads. (3) Fault Reporting: Each channel has an independent open-drain FAULT output that asserts low during overcurrent or overtemperature conditions. (4) Protection: Thermal shutdown protects against excessive power dissipation, and the device includes 15kV\/8kV system-level ESD protection on the output pins.","pin_description":"
